Figure 13 is an edge View of the coin slot restricting levers shown in Figure 12.

Figure 14 is a fragmentary face view illustrating a means for .adjusting the position of a rotor flange kerf.

In scales of the character hereinbefore referred to, when a person-steps on the load platform, a 55 spring Weighing-mechanism within the column acts to rotate a weight indicating dial having weight indicating characters which, preferably, are not visible from the exterior of the machine and power storing devices are actuated to store power for operating the ticket printing mechanism. A coin may then be deposited to release th'e ticket printing mechanism, whereupon a weight indicating ticket is printed and delivered.

The automatic mechanism of the scale is so constructed and arranged that the downward movement of the load platform which occurs when the platform is loaded by a person stepping thereon acts to move a power storing plunger upward to wind or store energy in the machine, and this movement of the plunger simultaneously feeds a .ticket portion into position for being printed and applies tension to the ticket printing and cut-off mechanism. Thereafter, upon deposit of a coin th'e applied tension actuates the ticket printing and cut-off mechanism and then releases the plunger so that it may move downward to initial position, during which downward movement the plunger resets the ticket printing and cut-off mechanism for a successive operation.

In the example of embodiment of the invention herein disclosed, the improved scale includes a base |50 on which is mounted a depressible platform |5| and from which a columnar casing |52 extends vertically. The casing includes a central crown extension |53 and carries a face plate |54 upon which instructions governing operation of the scale are applied. A coin slot |55 is provided at the left-hand side of the face plate. See Figure 1. The casing |52 also includes an ornamental face panel |56 having a window |52? formed therein through which dials of the inner mechanism of the scale can be viewed, and a coin and ticket delivery receptacle |58.

The weighing mechanism within the scale casing is substantially th'e same or fully equivalent to the scale mechanism disclosed in United States Letters Patent to Koch 1,969,466, issued August '7, 1934, and the parts of this mechanism herein disclosed and referred to are given the same reference characters applied to them in the said patent, so as to facilitate a clear understanding of the construction and operation of these parts.

Since the scale parts are disclosed in detail in the patent referred to, full detailed description of the construction and operation of these parts is though to be unnecessary in th'e present disclosure, and in order to facilitate this disclosure, the parts disclosed in the patent will be described by way of operation alone.

When a person steps upon the platform |5| of the scale, the following things happen. The winding rod 8 is moved upwardly and imparts a lifting movement to the lever 44, and the pawl 43 on said lever lifts the main power storing plunger 40. Upward movement of the rod 8 and the level` 44 also serves to release the latch |30 wh'ich is normally effective to prevent depression of the coin depressed released lever 96. See Figure 2.

Should a person step oif from the platform |5| without depositing a coin, the energy stored in the spring 93 by upward movement of the plunger 40 is retained by a latch pawl 48 which engages the lever 44. This latch pawl is released upon each normal descent of the plunger 40. The latch' |30 previously referred to prevents actuation of the scale parts by a coin until a person has stepped onto the platform |5|. See Figure 2.

Upward movement of the plunger 40 also actuates the ticket feed pawl 10 carried by the plunger 4U, by reason of engagement of said pawl with one or another of the pins carried by the ticket feed wheel '|3. The upward movement of the plunger 40 also loads the ticket cut-off knife and the ticket printing hammer actuating spring 93, these parts normally being held inactive by a latch 95. The cut-off knife and printing hammer equipments are generally designated K and H respectively.

Depression of the platform |5| also causes the rack 31 to move downwardly and impart weight indicating rotation to the printing wheel 25 but, as previously stated, the person standing on the platform cannot see the weight indication. See Figures 1 and 3.

When a coin is deposited in the slot by a person standing on the platform |5|, the coin, passing through' the coin slotway hereinafter to be described, engages and depresses the free end of the release lever 96. Depression of this lever serves to move the latch member |03 to the right, as viewed in Figure 2, thus freeing the trip lever |05 and permitting it to swing upwardly and impart a hammer blow effective to release the latch or trigger 95 serving to prevent actuation of the knife and hammer equipments K and H, and thus frees the energy stored in the spring 93 and brings about an actuation of th'e knife and hammer equipments effective to print and sever a ticket from the continuous strip of ticket material. Upward movement of the lever |05 also serves to release the pawl 43 and permit the plunger 40 to descend and reset the hammer H and ticket cutoff knife K equipments. See Figure 2.

The panel on which the weighing mechanism is mounted is herein designated |59 and is secured at its lateral edges to angular frame members |60 which are in turn secured to the side walls of the casing column |52. A similar panel is disclosed in the patent hereinbefore referred to, but in the present invention this panel includes an upward extension 6| which is secured upon the upper edge of the panel |59 by bracket strips |62. A removable rear panel or door |63 is provided, and through this door access can be had to the mechanism within the casing.

At the inside face and just beneath the coin slot |55, the face plate |54 is provided with a mounting boss |64 to which is aiiixed a mounting plate |65. The lateral edges of the plate |65 extend beyond the boss |54 and cooperate with the opposing rear wall portions of the face plate |54 in providing clearances in which coin pitching levers |66 are mounted. One such lever is mounted at each side of the boss and is pivoted at its lower end, as at |61, on the plate |65. Each lever |66 extends upwardly and traverses the coin slot 55, as at |68, extending inwardly of each end of said slot so as to restrict the coin passage therethrough. The -boss |64 serves as a limiting stop to limit movement of the levers |66 toward each other and thereby determines the extent to which said levers restrict the passage of coins through said slot. The levers |66 terminate at their upper ends in horizontally disposed ears |69, and a coil spring |'|0 is secured between these ears and serves to yieldably hold the levers in coin slot restricting relation. The plate |65 includes a horizontal, inwardly extended supporting ledge portion which serves to direct horizontally coins inserted through the coin slot.

Coins inserted through the slot |55 are pitched by the levers |66 across a wide gap |12 intervening the coin slot and the panel extension |6|. See Figure 7, Within said gap and in register with the coin slot, a debris trapping and coin reamasar.

turning-chute |13 is'secured to thefrontfaceof the pane1- |59 and the extensioni ||5|4 thereof; This-fchute-includes a forwardly extendedrlip |14 which-extends beneath theho-rizontal plate por'- tion |1'|-in the mannerbest illustrated infFigiu'ev 7. At itslower end, the chute |13 inclines laterally and downwardly, as at |15; and delivers-into the lower end of the ticket chute |16 also carriedby the panel |59. Bothchu'tes |15 and |1`|6 de*- liver through the front panel of the casing |52` intothe receptacle |58 hereinbeforereferred to. Seey Figure 3.

It will also be' observed by' referenceto Figure 3 that the panel |59 is provided with an opening |11 at thev juncture of the vertical and inclined portions'iof the chute |13 and |15, and the pur'- pose of this opening will'becomeapparent the' description progresses: A'l similar opening |18 'isprovidedfnearer the upper end' of thev chute |13" and; just below the coin receiver chute |19 se-V cured to the rear face of the panel `|59 and its extension 6|. See Figure 7. The upper' end wall oi` the chute |19 angled rearwardly andi downwardly above the panel extension' |=`6|, as at |89. For the purpose of diverting. coinspitched f-romthe coin slot' |55 into they receiving chute; H9 and immediately below the chute |19, there is provided a swingably mountedv chute section- |8|. The chute section |8| is effective at times to return coins to aper'son attempting to operatethe scale, and in accomplishing this function, such coins received in the chute |19 arediveited by the chute section |8| through the'panel opening |18 and into the coin return chute |13; The specific functioning of the chute section |8| will be described in detail hereinafter. The chute"y section is secured at |82 on the' rod |f83 rockably mounted in bearings |84' affix-ed to the rear face' of the panel |59. See Figure 2.

A bearing hub |85 is' secured to the rear? face of the panel |59 and carries anti-friction bearings |86 in which a shaftl |81 is rotatably mounted. The shaft |81 isprovided with an ax-ial bore |88 `and carries al pinion |'89p withinV the bearing hub. The hub isy cut away,'as at |99, at one sidev to render the pinion engageabl'e byv an actuating rack later to be referred to. See Figure 9.

Ahead |9| is formed on the front end of the shaft 81, and against this head a flange disk or rotor |92 is clamped by a nut |93. The' ange |94 of the rotor is provided with a receiving recess or kerf |95 at one point only in the circumference thereon The shaft |81 is also threaded at its rear end to receive a securing nut |96.

A mounting bar |91 is secured at |98V inspaced relation to the panel extension |6 I, and a-secondj mounting bar |99 is similarly secured,l as at 299,'v to the bar |91. The bars |91 and 299 rotatably support a shaft in axial alignment With the shaft |81 hereinbefore referred to. The shaft 29| carries an enlarged head 292 behind the rbar |91. A dial plate 293 having weight indicating graduations 294 applied to its front face is secured to a ilanged disk or rotor 295 similar in construction to the rotor hereinbefore described, and having its horizontal flange 296 equipped at one point only with a recess or kerf 291. yThe rotor and plate 295, 293 are carried by the shaft head 292.

The recess or kerf 291 in the rotor 295 is adapted normally to receive the outer end of a bar l298 pivoted intermediate its ends, as at 299, on the rotor 295. The inner end of the bar is' receivedinl af crosse-slotI 2:|9. formed in the head 292, andi a; compression spring 2TH mounted in the* receiving; socket .foi-'ined' in the shaft 29| normally presses the inner end of the lever 298 rearwardlyso astiok retain the outer end of the bar inthe-'diskkerf` 291', in the manner illustrated in' Figure 9i A large groovedpulleyV 2|2' is spline mounted oli-'the' shaft29`| and includes a hub 2|3 which isipres'sedintofrictional Contact with the bar |91 by' aA compression' spring 2|4 interposed between theront face-ot `the pulley and the rear face of thefba'xi` |99: A` coil spring belt 215 passes over the pulley 2|2r andover' a small pulley 2|6 secured upon' the-shaftl 2 |11 rotatably supported in the' faceplate: F511 and in the bracket 2|8 secured withinf the casing: column, in the manner best illustrated inFigures'Z and 8. A knob 2 I9 is secured' to' the shaft 2 I1- outside the casing, so that itcanf be" manipulated by a person seeking to use the scalerto=imp`aitrotation to the shaft 2 |1, and through the -belt 215 to the pulley 2|2 and the shaft- 29f| oniwhich it is mounted. A pointer 229 isflxedi to the lpanelv '|59 beneath the dial plate 293' and this pointer overlies the dial plate 293 and also the printingwheel 25 so as to indicate pos'itionsof said dialandwheel. By turning the khob"2|=9;.a=user of the-scale can impart rotation tothe rotor and"dial=295, 2:93 to recordk a guess of his'weight-i. and: tothus position the rotor kerf 291 and bar 2981in' 'accordancewith the weight guess.

A lever 22| is pivoted intermediate its ends, asfat 222', on ther extension |61 of the panel |59. Qrl'e'end ofthe lever is swingable in a confining slotin a bracket -22'3 secured to the panel extensiony |f6lf, asv illustrated in' Figure 2, and this end of thel lever carriesfan arcuate sector 224 in registry with aplunger 2215 which is reciprocable in the axial' bore |188 ofthe shaft |81 and which projects rearwardly from said bore in the manner illustrated. Figures 9 andv 10 of the drawings. Th'e'- sector includesv a plunger displacing .cam portion `226 anda horizontal flange portion 221 extendingv rearwardly beneath the lever 22|. A tension spring 228 is secured to the bracket 223 and tothe flange'l 221 and constantly tends to move" the lever 22| Ain a direction for depressing the sector 2 24"and causing thev cam portion thereof toy force`l` vthe plunger 225 forwardly. This movement of the lever is normally prevented by an abutment 229 adjustably ailixed to a rod 239 extended upwardly through a receiving aperture in the flange 221 andpivotally connected, as at 23|, atV its lower end with the crank arm 232 secured tothe printing hammer and cut-off knife carrying `shaft hereinafter designated 233. The abutment and 'rod equipment 229, 239 prevents lowering of the lever sector 224 until the control mechanisms are' properly released by the depositing' of a coin. The rod and abutment equipments 229, 239 also serve to reset the lever 2.2 land the sector 224 carried thereby to the normal' position illustrated in Figures 2 and 9 upon each resetting of the` printing hammer H and the .ticket cut-off knife K, as hereinbefore described.

At its r'other end, the lever 22| is connected with'a lift rod 2134, and the lower end of this rod passes through ari eye 235 in a crank extension 236 of 'the' rock 'sl-'raft 231. The rock shaft 231 has' fa-c'oin diverting vane 238 aixed thereto, and the shaft and vane equipments are mounted in a chiite vmember 239 which receives coins, as at 249ffi1'or`n thejlxed coin chute section 24| mounted in vertical `alignment with the chute section |19 and having an arcuate slotway 242 therein for receiving the end of the coin depressed release lever 96 which is bent at a right angle with relation to the main body of said lever. The end of the lever 96 thus projects into the coin slotway in position for being engaged and depressed by coins traveling downwardly therethrough. See Figures 2 and 4.

The chute structure 230 Aincludes a normal coin discharge passage 243 and a lateral diverter wall or bottom 244 which extends downwardly and to the left as viewed in Figure 4 and serves at times to divert coins onto a forwardly and downwardly inclined wall 245 leading through the panel opening |11 into the coin vreturn chute hereinbefore described. See Figures and 6.

A compression spring 246 is interposed between the crank eye 235 and an abutment 241 adjustably secured upon the lower end of the lift rod 234. Thus, each time the rod 234 is lifted by the lever 22|, the crank 236 will be lifted to move the diverter vane 238 from its normal vertical position to a tilted position for intercepting coins and diverting them from the normal discharge 243 into the diverter equipments 244 and 245 and the return chute portion |15.

The lift lever 44 is provided with an extension 248, and a cam finger 249 is pivotally mounted, as at 259, at the end of this extension. Spring means 25| serves to normally hold the cam nger in the position illustrated in Figure 4 of the drawings, an abutment 252 serves to define this normal position by engagement with the outer end of the extension 248, and the nger includes a cam nose portion 253 having an upper inclined cam portion 254 and a lower oppositely inclined cam portion 255. Each time the lift lever eX- tension 248 is moved downwardly after a scale operation to its normal position, illustrated in Figure 4 of the drawings, the cam surface 255 thereof serves to return the crank 236 to a position for holding the diverter vane 238 vertically. Said cam surface likewise yieldably holds the vane in this normal position, but yields to permit movement of the vane to its tilted or coin diverting position whenever the rod 234 is lifted upwardly. Whenever the rod is so lifted and the crank 236 is lifted to tilt the vane, the upper cam surface 254 serves to yieldably hold the vane in the tilted position, and prevents rebounding of the vane from its coin diverting position.

A rack member` 256 meshes with the pinion |89 on the shaft |81 and is slidable in a bracket 251 secured to the panel extension IGI. The rack 256 is held against the pinion by a roller 258 xedly supported on the panel extension, and this rack moves simultaneously with the rack 31 of the weighing mechanism hereinbefore referred to, because of being connected with the rack 31 through the medium of a thrust link 259. See Figure. 2.

The invention includes a novel ribbon mounting and novel means for presenting fresh portions of the ribbon to the ticket printing mechanisms at relatively infrequent intervals. This equipment includes a frictionally mounted pay-off spool 260 on which one end of an inked ribbon 26| is wound. The paid-off end of the ribbon passes over guides 262 spaced beneath the printing wheel 25 and over suitably positioned guides 263 which direct it to the take-up or feed spool 264. The spool 264 is mounted on a shaft 265 freely rotatably mounted, as at 266, in the panel eX- tension IBI. In order to facilitate mounting and removal of the spool, the shaft includes a threadably mountedremovable section 261 equipped with a knurled turning head 268 which also serves as a spool retainer. The spool 264 includes face plates 259 joined in spaced relation by distance rods 218, and a ratchet wheel 21| is connected in driving relation with the spool through the medium of a driving lug 212 which extends from the wheel into a receiving aperture in one of the spool plates. A larger diameter ratchet wheel 213 is freely rotatable about the shaft 285, and it will be observed by reference to Figures 8 and l1 that the root of each ratchet tooth save one on the wheel 213 is spaced the same or a slightly greater distance from the wheel axis than the peripheral extremities of the teeth on the smaller wheel 21 One tooth of the wheel 213 is made deeper than the remaining teeth thereon, and this deep tooth is designated 214. The purpose of this deep tooth will soon be described. Spring check pawls 215 are secured, as at 216, to the panel extension IGI in position for engaging and preventing retrograde movement of both of the ratchet wheels 21| and 213.

A vertical opening 218 is formed in the panel extension |S| to receive and accommodate movement of a horizontal extension 219 from the actuator pawl 289 which is pivotally mounted, as at 28|, at the upper end of the plunger 49. See Figures 8 and 1l. The pawl 289 includes a rearwardly extended leg 282 disposed in parallel relation to the main body of the pawl and terminating at its upper end in an upward and rearward flare 283. The pawl portion 219 is constantly urged toward the ratchet wheels by a tension spring, and it will be obvious that each time the plunger 40 is moved to an upper extremity of its range of movement, the pawl portion 219 will engage and impart a step movement to the ratchet wheel 213. Only when the pawl portion 219 enters the deep notch 214 in the ratchet wheel 2113, however, will said pawl portion be permitted to move inwardly far enough to engage and impart a step movement to the ratchet wheel 21|, and thus a step movement will be imparted to said ratchet wheel 21| and to the ribbon once for each sixteen reciprocations of the plunger 49. Obviously, the relation of the plunger reciprocations and the ribbon feed steps can be varied at will by altering the relation of the teeth on the respective ratchet wheels.

The spaced leg and body portions 282, 289 of the pawl straddle a weighted, generally horizontal arm 284 of a bell crank lever 285 pivoted, as at 286, on the panel |59. The other generally vertical leg 281 of the bell crank lever is equipped with a latch shoulder 288 engageable over a latch arm 289 extended rearwardly from the rock shaft |83 hereinbefore referred to.

The tension spring by which the pawl 289 is yieldably urged toward the ratchet wheels is designated 299 and is secured to the pawl and to the pin which forms the pivotal mounting for the bell crank lever 285. A tension spring 29| is connected to the same pin and to the free end of the latch arm 289, and constantly urges the shaft |83 in the direction for presenting the coin chute section |8| in its coin chute aligned position, that is in position for aligning with and forming a through passage for coins with the chute portion |13 and the chute portion 24|. See Figures 2 and '1. A crank arm 252 is secured to the shaft |23 and is engaged by a lug 293 on the plunger 46| each time the plunger moves downwardly to rock the shaft |33 and position magazine (not shown).

Amarcati `Anotherlatch 294 is engageable with the latch arm 289 whenever no ticket material is present `in the machine, thereby to assure vreturnl of a coin rto a person seeking a weight indication bearing ticket when no such ticket is procurable. The latch 294 vis secured-upon a-shaft 295 rockably mounted inthe panel |59. ,Thelatch 294 is lmounted at the rear face of the panel, and the shaft 295 extends yforwardly through the panel land carries a vweighted lever 298 which constantly vtends to move the latch lever to the latch arm engaging position. See Figures 2 and 3. The lever -296 is normally held upwardly in a position for displacing the latch from engagement with the latch arm `289 by engagement of the weighted lever with and the supporting thereof by the ticket strip 291. The ticket strip is fed through a guideway 298 from a suitable When the ticket material becomes `exhausted the weight '296 normally held up by the ticket strip gravitates, rocks the shaft 295-and engages the latch '294 over the arm 289, thereby preventing displacement of the chute section |8| from its coin return position illustratedy in Figure 7.

'I'he coin chute proper 24| into which the tiltable coin chute section |8| delivers, includes a tortuous passage or a coin fall delaying section 300, and normally delivers at its lower end into the coin discharge passage 243, the coin falling laterally off the end of the coin depressed release leveri96 at 240.

In Figure 14 of the drawings, I have illustrated a slightly modified means for providing -the'slot or kerf in the rotor ange |94. In this modified form of the invention, the kerf is'formed in a sector 30| which is adjustably mounted, as at 302, on the rotor. By utilizing an adjustably mounted :kerf-equipped sector, alignment of the kerfs |95 and 201 in the respective rotors is greatly facilitated in the initial setting'up of the machine. It will be observed by reference to Figure 14 that the rotor |92ais inithis instance provided withl an enlarged flange opening 303 and by adjustment of the position of the sector 30|, the position of the kerf |95a in the sector can be altered at will with relation to said the receptacle |58 without clogging or in any wise interfering with proper operation ofthe mechanisms of the scale.

A person using the improved scale structure herein disclosed can,v by manipulation Y"of the knob 2|9, Aadjust thedial plate 203 .torecord brindicate his guess of his weight. ,It willbe remembered that upon mounting the platform |I, the

-plunger40 is lifted to store energy in the spring 93, the latch |30 which holds the-release lever 96` against depression is removed from its holding position, the lift lever extension 2,48 is lowered to assure the normal vertical` or non-diverting position of the vane y238, and theracks -31 Aand 2,56 ,are-lifted ,to record the weight .on` the plat- -form and position the printing wheel and the rotor |92 to indicate -or record said weight.

Upon depositing of a coin, assuming thatthe plunger 40 has been elevated the full distance desirable to properly store energy in the spring vl93 and sufficient to displace the weighted lever L284-and the 4latch porti'onf288 thereof Aso as to permitthe chute section |8| to move into coin and slot registering position, said coin will fall through the coin chute and depress the lever `96, thereby releasing the member |03.and-permit ting the member |05 to forcibly engage and release the latch or trigger 95 yto thereby permit the spring ..93 to actuate the printing hammer and the ticket cut-off knife.

As the crank arm `232moves downwardlyupon actuation of therhammer and knife equipments, the support 229 is removed from beneath the flange 221 ofthe lever 22|, and the lever is free to befmoved downwardly by the spring V228 unless such downward movement is obstructed by the projecting end of the plunger 225. Downward movement of the leverwill be so obstructed unless the person using the scale has accurately guessed his-weight, thereby occasioning perfect registry of thel rotor sections 201 and |95 and permittingthe movement of the outer end of the bar 208 from the kerf y201 into the kerf |95, thereby freeing the front end of the plunger 225. Whenever the plunger 225 istso freed, the lever 22| snaps downwardly andvlifts `the rod 234, thereby positioning the vane 238 for eX-. tending into the coin slotway 243 to divert ythe coin and deliver it over the surfaces `244 and 245 into the coin return chute portion |15.

Movement of the lever |05r also releases the pawl 43 and allows the plunger to descend and reset the printing hammer and cutting knife equipments. Resetting of these equipments moves the crank .arm 232 upwardly and causes the abutment229 toreset the lever 22| to the normal position first described. lDownward movement of the plunger also brings about engagement between the elements 293 and 292, causing the rock shaft |83 to be latched by the member `288 in positionfor tilting the coin slot section |8| to the coin returning position.

It `will be obvious that various changes and modifications can be made in the structures herein disclosed without departing from the spirit and scope of the invention as deiined in the appended claims.
